j fb whom tummy .concer/'ai ,heating boththe fuel and air supplied 4to device for Be it mlown thatl, Fiano. aciti zenvof the United States, and a residentof .flmaha, in thecounty of Douglas and State yof Flebrasha, have `invented certain new and useful improvements in Carburetor Accessories, of whichthe following is a specicall/fy Ainvention ,relates to charge-forming devices for internal combustion engines, and

particularly to auxiliary means adapted for4 use in connectionwith carbureterls, for prethe carbureter, and for supplying and vaporiain water to be mixed with the air for huniidi fr ing the same before it enters the carbureter proper. llt is the object of my invention to provide a simple and efficient j jpierforming each of the above mentioned notions, the device being constructed and adapted for'connection with the exhaust pipeof the engine, so that the necessary heat is supplied by the exhaust gases or combustion products fromf'the en-4 e. j ln the accompanymgdrawings Figure l j is a partially diagraatic side view of a dll j device embodying my invention, .together with the various mechanism connected andv associated with` the same when in use, Fig. 2 is a detail side elevation of the heatin degvice, Fig. 3 is a transverse section o 'the same onl the plane of the line 3--3 of Fig. 2

. more lvolatile fuel such as `gasolene. From` the tank 8 `a connecting supply-pipe 9- is eutended directly to and suitably connected lwithjthe carburetor. rlhere are also shown `a part of the intalre pipe l which extends from the carburetor .tothe en ne, a part of the exhaust-pipe ll Vof the engine, the mumer l2 with which the exhaust-pipe is connected, .the radiator 13 used in the water-cooling system for the engine, `a water circulating pump le, and a part of the dash or foot- `board l yof the vehicle. All of the foregoing parts are indicated in the drawing merely for the purpose of showing their relation to the devices embodying my inveneing in two portions f6 and i7 secured together longitudinally, and having the ends (thereof connected by means of the caps le with thev portions of the exhaust-pipe ll through which the heated gases are supplied thereto and discharged therefrom. The central passage through the jaclreted hue. portionsv 16 land l? is ribbed or ojuatrefoliate in section, the outer' parts or jackets being cylindrical, and the jackets and central due parts being connected with eachother by integral end-portions,- The caps le are ap proximately semi-spherical in form, the ,diameter thereof being'the same as zthatof the j achete of the due portions against wh1ch they are htted. ht the edges of the caps are perforate lugs i9, and similar lugsll,

having threaded openings therein, are provided at the ends of the long nuesection le.

'lhe short ue-section ll' has a single set of perforate lugs 2l disposed intermediate of its ende.` Screws 222 extend through the lugs lll of one cap, entering the threaded openings ofi the lugs at the adjacent end-of the Hue-section 16 to secure the cap upon said duefsection. ht the other rend, long ree y screws 23 pass through the lugs 19 of the cap, thence through the lugs 21 ofthe Short flue-section 17, and then enter the threaded openings of the lugs 20 at the adjacent end of the section 16. The short flue-Section is thus secured between the cap and the end of the long flue-section. At the central part of each cap 18 is a clamp-nipple 24: having a slot or kerf at one side, and provided with a screw 25 which may be tightened to close the kerf and clamp the nipple onto the exhaust-pipe 11.

On the lower side of the jacket of the flue-section 16, near one end thereof, is a nipple or tubular boss 26, and near the opposite end of said flue-section on the upper side thereof `is a similar nipple 27 with' which is connected a tubular elbow 28,. From the latter a flexible pipe 29 is extended to the air-inlet of the carbureter 6, so

that the air which enters the carbureter must bev drawn through the heater, Ventering the jacket of the section 16 at the nippleV 26, thence circulating through the space within the jacket, and then passing through the elbow 28 and pipe 29 to the carbureter.

A certain quantity of water is supplied. to the heater, so as to be vaporized therein and mixed with the heated air passing to the carbureter, as follows: From the dischargepipe of the water-circulating pump 14, a small pipe 30 is extended to a sight-feed valve 31 arranged on the dash or foot-board 15 of the vehicle, as shown. From said valve 31 another small pipe 32 is extended to the heater and connected with a nipple 33 which is arranged adjacent to the nipple 27 on the jacketed-section 16. The ow of water from the pump through the tubes 30 and 32 is regulated by thevalve 31, and the water enters the jacket of the heater so as to fall onto the heated inner flue-.portion thereof, where it is vaporized and mingles with the' air so as to moisten and humidify the same.

The short jacketed Hue-section 17 is used for heating the fuel from the supply-tank 7 before said fuel passes to the carbureter. 'From said tank 7 a small feed-pipe 34 is extended to and connected with a nipple 35 at one side of the jacket of said Hue-section 17 so that the fuel is supplied through said pipe to the space within the jacket, as shown in Fig. 3. A pipe 36 is connected with another nipple 37 on the side of said jacket, and extends therefrom to an opening in the elbow 28, passing into the elbowas shown in Fig. 2, and thence through the pipe 29 to -the carbureter. The fuel, becoming heated while within the jacket-chamber of.

the section 17, passes through the pipe 36 to the carbureter, and, as the greater portion yof said pipe 36 is inclosed. by the pipe 29 and thus. surrounded by the heated air, the fuel is maintained in a heated condition.

When installing the heating device, besides supplying the required connecting piping therefor, it is merely necessary to remove a section of the exhaust-pipe 11, 'and to substitute the heater for the removed portion of the exhaust-pipe'by clamping the caps 18 onto the ends of the remaining por-l tions of the pi e. From the foregoing it will be apparent t at my invention provides a simple and e'ective heating and humidifying device which, in connection with a suitable carbureter, may be readily attached to any motor-vehicle now in common use, where such vehicle employs an internalcombustion engine for its motive power.

N ow, having described my invention, what I claim and desire to secure by Letters Patent is:

l. A fuel and air heating and humidifying device for carbureters, comprising a plurality of jacketed Hue-sections having central longitudinal passages, means for connecting the same serially in the exhaust-line of an engine, means for directing air to a carbureter from the jacket-space of one of the flue-sections, means'for supplying water to said jacket-space means for supplying liquid fuel to the jacket-space .of another flue-section, and means for directing the fuel from said jacket-space to the carbureter,

said fuel-directing means being arranged to' be heated by the air from the first-named jacket-space.

2. ln a device of the class described, a plurality-of integral jacketed flue-sections having longitudinal passages and jacketspaces surrounding the same, means, for connecting said Hue-sections serially in the exhaust-line of an engine, means for directing air and liquid fuel into the respective jacket-spaces, and means for directing the air and fuel from said jacket-spaces to a carbureter.

3. ln a device of the class described, a longitudinally-ribbed Hue having an inclosing jacket spaced therefrom and connected therewith by integral imperforate end-portions extending transversely to the axis thereof, caps adapted to' t upon the ends of said flue and detachably connected therewith, clamping means on said caps for detachably retaining the same upon the ends of a pipe, and means forming air inlet and outlet passages from the space within the jacket.

4f. In a device of the class described, a flue-section having a longitudinal ribbed passage through it, a jacket inclosing said flue-section and forming a chamber around Lemme the chamber of said Second Hue-section, and d 5 caps removably connected with the ends of the rst flue-section, the second Hue-section 4 being clamped between the end of the rst and one of said caps, and Said caps being detaelmbly connected with men's tot' admitting and dsebm'ging u heating meduln 1 0 from the longitudinal passage through the Hue-sections.,
